Theme-It Issue on Mac

Theme-It Issue on Mac

I just purchased Theme-It and am having issues with a javascript error and no preview showing. I've tried deleting the .dat file, but that didn't help. I have attached a screenshot of the javascript error. I would really appreciate any assistance you can give to me asap. Thanks.

I did download the beta and it seems to have fixed it. It was not on any particular file that this was happening but on ALL of the files I opened. When I removed the original plugin and reinstalled using the beta, it fixed it. I'm on Mac OSX Snow Leopard and Dreamweaver CS4. Thanks!
